Answer:
La piedra alcanza una rapidez de 196.14 metros por segundo y una distancia recorrida de 1961.4 metros en 20 segundos.
Explanation:
Si se excluye los efectos del arrastre por la viscosidad del aire, la piedra experimenta un movimiento de caída libre, es decir, que la piedra es acelerada por la gravedad terrestre. La distancia recorrida y la rapidez final de la piedra pueden obtenerse con la ayuda de las siguientes ecuaciones cinemáticas:
Donde:
, 
- Rapideces final e inicial de la piedra, medidas en metros por segundo.
- Tiempo, medido en segundos.
- Aceleración gravitacional, medida en metros por segundo al cuadrado.
. 
- Posiciones final e inicial de la piedra, medidos en metros.
Si 
, 
, 
, entonces:
La piedra alcanza una rapidez de 196.14 metros por segundo y una distancia recorrida de 1961.4 metros en 20 segundos.
Answer:
4.47
Explanation:
Given data
vector 1 = 2m/s
vector 2= 4 m/s
The expression for the magnitude of two vectors is
|a| = √v1^2+ v2^2
substitute
|a| = √2^2+ 4^2
|a| = √4+ 16
|a| = √20
|a| = 4.47
Hence the magnitude of the two vectors is 4.47
Welll ... if you read the question, you'll see what a jumbled mess you actually
posted, but I think I can pull enough out of it to give you some answers.
<span>One
light bulb in a string of lights goes out. This causes all of the
other
lights in the string to also go out. The entire string of lights
must be one series circuit.
2. When a switch is turned from the off to the on position,
an open circuit is changed to a closed circuit.
3.Early telephone poles had wires that connected inside bell-shaped
glass enclosures like the ones shown below. (nothing is shown below)
several bell-shaped glass enclosures
These glass enclosures helped to
keep the electric current from moving
outside the circuit of wires. The
glass enclosures were used as insulators.
4.Use Ohm’s Law
to determine the resistance in a circuit if the
voltage is 12.0 volts
and the current is 4.0 amps.
Ohms law: Resistance = (voltage) / (current)
= (12.0 v) / (4.0 amp)
= 3 ohms .
5. "In a closed circuit, the
current only flows from the power source
to an electrical device such
as a lamp."
This statement is false. The current eventually has to get back
to the power source. If it doesn't then there's no 'circuit', and
nothing works. That's a big part of the reason why the plug
has 2 prongs on it, and the cord from the plug to the lamp
has 2 wires in it. </span>
Answer:
The total binding energy of the nucleus with 200 nucleons more than the total binding energy of the nucleus with 60 nucleons
Explanation:
Binding energy can be given by the formula:
Binding energy = Binding energy per nucleon * Number of nucleons
This means that if the binding energy per nucleon = x MeV
Where x is a positive real number
The nucleus with 60 nucleons will have Binding energy = 60x MeV
The nucleus with 200 nucleons will have binding energy = 200x MeV
For a +ve x, 200x > 60x
